Instead of systematic checks, police would randomly stop vehicles on the German side and ask drivers to show “a negative test and their online entry registration”, he said.
Germany has grown increasingly concerned in recent weeks about the rapid spread of new, more contagious strains of the coronavirus, especially those first detected in Britain and South Africa.
The coronavirus, including the more dangerous South African variant, is spreading faster in Moselle than elsewhere in France but French officials have pleaded with Berlin to avoid a full closure of the border.
The German classification “normally implies the extremely strict measure of a quasi-closure of borders”, France’s European Affairs minister Clement Beaune said Sunday.
“We don’t want that,” he said, adding that talks were ongoing with Berlin to find solutions for the roughly 16,000 commuters who cross from Moselle into Germany’s Saarland and Rhineland-Palatine states every day.
The German interior ministry spokesman said the two countries would discuss details of the border implications on Monday.
Asked why the French checks would not be as stringent as those along the Czech and Austrian frontiers, the spokesman said Saarland and Rhineland-Palatine had not requested border closures.
“And there is a good cooperation between the affected German and French regions,” he added.
